Richard Cochran e1272f541c ACPI/processor: Avoid STARTING/DYING actions in a more logical way 
As part of the hotplug cleanup, the CPU_STARTING/DYING actions are going
away soon.  This driver needlessly uses those two macro, and so this patch
replaces that code with something more sensible.

Commit:

  8da8373447 ("ACPI / processor: Fix STARTING/DYING action in acpi_cpu_soft_notify()")

added checks for those two actions, because the notification callback can
sleep, causing a hung CPU. This patch instead checks for the ONLINE/DEAD
actions, which are the ones that are handled by the driver in the first
place.

Sebastian Andrzej Siewior 251a5fd64b x86/kvm/kvmclock: Convert to hotplug state machine 
Install the callbacks via the state machine and let the core invoke
the callbacks on the already online CPUs.

We assumed that the priority ordering was ment to invoke the online
callback as the last step. In the original code this also invoked the
down prepare callback as the last step. With the symmetric state
machine the down prepare callback is now the first step.

Anna-Maria Gleixner 162e52a117 KVM/x86: Remove superfluous SMP function call 
Since the following commit:

  1cf4f629d9 ("cpu/hotplug: Move online calls to hotplugged cpu")

... the CPU_ONLINE and CPU_DOWN_PREPARE notifiers are always run on the hot
plugged CPU, and as of commit:

  3b9d6da67e ("cpu/hotplug: Fix rollback during error-out in __cpu_disable()")

the CPU_DOWN_FAILED notifier also runs on the hot plugged CPU.  This patch
converts the SMP functional calls into direct calls.

smp_function_call_single() executes the function with interrupts
disabled. This calling convention is not preserved because there
is no reason to do so.
